dimming 2 seperate 12v leds using wireless remote control dimmers

This is just a possible.
Are the two control and slave units sealed? or are they clipped together packages and may have a small tuning switch or trim pot inside.

If they are openable, it may be possible to adjust the code pulse trim on one control and then align it's slave accordingly to the same frequency.
Only a thought it may be possible.

If they are the ones on ebay for about $8 ( same as the ones sold in a 4wd LED shop for about $45, I bought some and they do work great but are all the same frequency and codes. In the end I used one remote and one manual one with a knob and actually prefer the knob one more....

I did look for different brands / frequencies but could not find any.

Another note, they are pwm and save power. But they are very noisy electrically if you have an AM or HF radio.

When you consider how cheap these things are, don't expect too much.

Of course they will all be on the same frequecy.

NOW
I work with a arays of TVs at the moment...and yess all the remotes workl all the TVS.

there are a couple of tricks.

1 get real close to the reciever you want to work with.....sort of defeats the purpose don't it.

2 Put shutters on the on the recieving eye so it only accepts light from a narrow range....little bits of cardboard or dunny tubes will do it.

3 put ya remote in a tube...a long one so it only sends out a narrow beam.

all only marginally effective.

AHH...this wireless thing....its the cargo cult and the emporors new clothes combined of the new melenium.

Everybody want stuff to be wireless...realy its only one step short of harry potter with a magic wand.
There are very real limits to everything wireless.....and good reliable wireless aint cheap.

cheers

Thanks everyone for your input. I have pulled the slaves out of their boxes and they appear to have pots, but have yet to check the remotes themselves. My relative is into electronics so I might ask him to have a look at this for me. If it works out I will post the results. The remotes operate on radio frequency, so I dont know if it would be possible to shield the remote or slave to only accept one signal. The other option is using wired, but this will be more difficult due to feeding wire through walls. Wish me luck!!
